CLUTCH LOOK FOR :EFIOTOR VEHICLES.

Application filed March 2, 1922.

To (4Z2 whom it may camera:

it known that l. LLOYD .i intrnivo GALAIH'E. a citizen of the Unit-cdtitatcs. and aresident of Freeport, in the county at Stephenson and hate at Illinois have in-- vented a new and useful in'iprovement in Clutch Tool 1 tor Motor Vehicles. of which the tollmvinn" is t'ull. clear. and exact description.

My invention relates to improvements in clutch locks or motor vehicles. and it consists in the condiinations. constructions and arrangements he. In dcscribec and clain' ed:

An object of my invention is to provide a. device of the character de crihed. in which means is provided for positively locking the transmission clutch in a position to disconnect the actor from the transmission mechanism.

9 A t'urthcr object oi? my in ention to provide a device of the character descrihed. which may be readily and easily attached to the standard type oi motor vehicle in common use.

A further object of my invention is to provide a device of the character described which is entirely concealed from view with the exception of the foot plunger and the a di acent spring: lock.

further object. of my invention is to provide a device ot the character described, which is simple to operate. which is compact in form and thoroughly practical for the purpose intended.

5 Other objects and advantages will appear in the following: specification. and the novel features oi the invention will he particula'rlv pointed out in the appended claim.

My invention is illustrated in the accompanyinc' drawings. forming part of this application. in which Fig. 1 is sectional view of an emhodiment 0'? my invention. and

2 is a sectional view along the line 22 of Fig. 1.

In carrying out my invention. 1 make use of a motor vehicle having a power plant, which is adapted to drive the car through a clutch mechanism, which clutch mechanism is operative to disconnect the engine from the transmission mechanism by pressing a foot lever 1. The foot lever 1 is carried by a transverse rock shaft 2. which shaft is connected directly to the clutch mechanism (not shown).

When a toot pedal 3 disposerjl at the outer Serial No. 540,456.

end a or the lever 1 is manually pressed. the.

lever 1 will assume the position in dotted lines in 1 and the clutch mechanism (not shown) will cause the engine to he disconnected trom the transmission mechanism. The transm ion mechanism is housed ithin a casino 5. y present invention consists of a litmus ror locking the shaft 2 in a position shown in dotted lines i the drawing. thus locking the clutch so the 3. c engine is out of eupja cment with the t i'i'iission of the car. Tiis means comprises a cylindrica sleeve 6 having; one end 7 close-cl. The sleeve 6 is provided with a pair of downwm l y extendinc luo s 8. The 's 8 have threaded h 9 in side thei l. l i ith reference to Fig. 9 it will be seen that the bores pr, 'ide means tor secu; the sleeve 6 its adjusted horizontal position adjacent the top of the transmission casi o; 5. This is done by inserting threaded halts 10 from the inner side of the casino; it being necessary to first remove the top plate 11 of the casing,

11. pair of hushinets 12 and 13 are disposed within the sleeves 6 and provide bearing:

means for a horizontally and slidahly dis-' is pressed downwardly. that the shaft 14;

will move outwardly in. the bushing-s 13 and 14; to the position shown in dotted lines in Fig. 1.

Means for locking the shaft 14: in the po sition shown in the dotted lines is provided in a vertical plunger 19 disposed within a vertical sleeve 20. which sleeve 20 is carried by the sleeve 6. A spiral spring 21 serves to normally hold the plunger 19 in an elevated position i. e. out of engagement with the joint 14. A 'foot pedal. 22 is disposed at the upper end 01"" a small. vertical stem 23 disposed at the upper end of the plunger 19. When the foot pedal 22 is pressed downwardly as by the heel of the driver, the plunger 19 will be forced against the action of the spring 21 into the sleeve 6 and to the position shown in dotted lines in Fig. 1.

" Shaft 14,.

Means for locking the plunger 19 when pressed downwardly is provided in a spring actuated lock mechanism 24L having a plunger 25, which plunger is pressed into engagement with a notch 26 at the top of the plunger 19 as the plunger is pressed downwardly,

In order to release the plunger 25 from the notch 26, it is necessary to employ a key (not shown), which key is adapted to fit the key slot 27 of the spring lock mechanism 24 and by means of which the plunger 25 may be withdrawn.

From the foregoing description of the various parts (it the device, the operation thereof may be readily understood. When it is desired to loclrthe motor vehicle, upon which my invention is used, it is merely necessary to press the clutch foot pedal downwardly, as in disengaging the clutch. The foot is held upon the pedal 3 with the lever in the position shown in dotted lines in Fig. 1. The other foot is then brought into engagement with the foot pedal 22. This foot pedal 22 is then pressed downwardly. In doing so, the plunger 19 will be moved against the action of the spring 21 and will assume a position immediately in'the rear of the horizontal shaft 14. The plunger 19 will remain in this position by engagement of the plunger 25 and the notch 26 of the plunger 19 in the manner heretofore described. The foot may then be removed from the pedal 22 and the other foot removed from the pedal 3. It will be noted that because the horizontal shaft let cannot recede in its bushings 12 and 13, that the lever 1 will be held in the position shown in dotted lines and the clutch will be locked in its disengaged position.

I claim:

A deviceoi the character described com prising a sleeve adapted to be mounted on a motor vehicle. a shaft mounted for re ciprocation within the sleeve, said shaftbeing adapted for connection with the clutch operatingpedal of said motor vehicle, a second sleeve perpendicular to said first named sleeve and communicating therewith, a spring pressed plunger disposed in said perpendicular sleeve and arranged to be manually projected into said first named sleeve when said shaft disposed at one end of its reciprocated movement and out or" registration with said ierpendicular sleeve whereby said shaft may abut said plunger in said perpendicular sleeve and be stopped from further movement in said sleeve, and a lock for securing said plunger down against the'action of said spring, said lock being arranged to release said plunger at will,
